To this end The machine shown inthe drawingscomprises 5 a bundle or pile is formed with a. number of strips a tableI (Figure 1), having aligned on its side of paper which is equal to thenumber of sheets the reels such as 2, 3, provided with strips of cig:

The proper position is obtained by unlockingthe bolts through an adjusting screw 31 which is shown in dotted linesin Figure 4. The said screw enables moving the support in the directionof the arrow 54 without changing the obliquity of the cylinder 25.

Owing to said adjustment, the bundle 30 is exactly superimposed on abundle 38 (Figures 5 and 6) which comes from the preceding reels. The

apparatus comprises a row of upper reels 39, 40,

4 I, arranged side by side and with their axes such as 5 (Figure 1) inalignment with each other. Above the said row is arranged another row ofreels 3, 42, 43. For sake of cle'arness, only a number of the reels ofeach row is shown in Figures 5 and 6, but in fact the upper and lowerrows extend along the entire machine.

The bundle 38 is driven by a belt 44 running over the pulleys 45, 46. Ittravels from left to right (Figures 5 and 6) and is supplied with twostrips at each roller 25; The total bundle coming out at 41 isconstituted by a number of strips which is equal to the number ofcigarette paper sheets which will be comprised in each block.

The said bundle is carried over a, drum 48 (Figure 5) and returns fromright to left. It is then provided with a board strip 49 intended toform the cover of the blocks. To this end, the strip 49 is wider (Figure6) than twice the width of the bundle The strip 49 is folded over thesaid bundle along the path comprised between the drum 48, and thefolding means such as 50. The bundle thus wrapped is driven by thecylinders 5!, 52, and subsequently sectioned by a device which isdiagrammatically shown at 53 (Figures 5 and 6). 7

Having now particularly described and ascertained the nature of myinvention and in what manner the same is to be performed, I declare thatwhat I claim is:

1. An apparatus for manufacturing cigarette paper blocks comprising aseries of drums for holding webs of cigarette paper, guiding means forthe edges of each web located, at the point where each web leaves itsdrum and means for mounting said drums so that said drums may rotatefreely on their axes and move longitudinally of said axes.

2. An apparatus for manufacturing cigarette paper blocks comprising adrum for holding a web of cigarette paper, a roller, flanges upon saidroller guiding the edges of the web of paper located at the point wheresaid web leaves said drum, means urging said roller with said flangesagainst the web upon said drum and means for mounting said drum so thatsaid drum may rotate freely on its axis and also move longitudinally ofits axis.

3. An apparatus for manufacturing cigarette paper blocks comprising aseries of drums for holding webs of cigarette paper, guiding means forthe edges of each web located at the point where each web leaves itsdrum, means for mounting said drums so that said rollers may rotatefreely on their axes and move longitudinally of said axes, endlessfeeding means between which said webs are led after leaving said drums,a direction changing roller for said webs for changing the direction ofsaid webs after leaving said endless feeding means and endless feedingmeans for said webs located at substantially right angles to said firstmentioned feeding means.

4. An apparatus for manufacturing cigarette paper blocks comprising aseries of drums for holding webs of cigarette. paper, means for mountingsaid drums so that said drums may rotate freely on their axes and movelongitudinally of said axes, fixed guiding means for each web located atthe point where each web leaves its drum, means for feeding said websafter leaving said guiding means, means for changing the direction ofsaid webs after leaving said feeding means and a second feeding meansfor aligning all said webs in a compact bundle.
